Air-conditioning system

Abstract

An air-conditioning system includes air-conditioning apparatuses each including an air-conditioning device involved in air conditioning of an air-conditioned space, and a centralized management remote controller configured to perform rotation control in which an operating state of each of the air-conditioning apparatuses is controlled by being set to be switched for each rotation time. The centralized management remote controller includes a centralized management remote controller communication unit configured to communicate with the air-conditioning device connected by a communication line, and a centralized management remote controller control unit configured to set the rotation time depending on an air conditioning load of each of the air-conditioning apparatuses based on data transmitted from the air-conditioning device through communications with the centralized management remote controller communication unit when the centralized management remote controller control unit sets the operating state of each of the air-conditioning apparatuses.

1 . An air-conditioning system comprising:
 air-conditioning apparatuses each including an air-conditioning device involved in air conditioning of an air-conditioned space;   a management device configured to perform rotation control in which an operating state of each of the air-conditioning apparatuses is controlled by being set to be switched for each rotation interval; and   at least one of an illuminance sensor and a human sensor installed in the air-conditioned space,   the management device including   a communication unit configured to communicate with the air-conditioning device, and   a controller configured to set the rotation interval depending on an air conditioning load of each of the air-conditioning apparatuses based on data transmitted from the air-conditioning device through communications with the communication unit when the controller sets the operating state of each of the air-conditioning apparatuses.   
     
     
         2 . The air-conditioning system of  claim 1 , wherein each of the air-conditioning apparatuses includes an air-conditioning remote controller including at least one of the illuminance sensor and the human sensor. 
     
     
         3 . The air-conditioning system of  claim 1 , wherein
 the management device has data in which a setting and a reference value are associated with each other for each control content of the operating state performed in the rotation control, and   the controller converts data transmitted from the air-conditioning device into a numerical value for each control content of the rotation control, and sets the operating state and the rotation interval based on the setting associated with the reference value corresponding to the numerical value.   
     
     
         4 . The air-conditioning system of  claim 1 , wherein
 the management device further includes a storage unit configured to store the rotation interval in each of the air-conditioning apparatuses, and   when the controller determines that power consumption of the entire air-conditioning system exceeds a prescribed power amount, the controller determines an order of the air-conditioning apparatuses to which a demand control command is transmitted to keep the power consumption within the prescribed power amount, based on the rotation intervals of the air-conditioning apparatuses stored in the storage unit.   
     
     
         5 . The air-conditioning system of  claim 1 , wherein the controller is configured to decrease the rotation interval when the number of people in the air-conditioned space detected by the human sensor is larger than a predetermined number of people. 
     
     
         6 . The air-conditioning system of  claim 1 , wherein the controller is configured to increase the rotation interval when illuminance in the air-conditioned space detected by the illuminance sensor is smaller than a predetermined illuminance. 
     
     
         7 . The air-conditioning system of  claim 1 , wherein the controller is configured to decrease an operation time of the air-conditioning device when illuminance in the air-conditioned space detected by the illuminance sensor is smaller than a predetermined illuminance. 
     
     
         8 . The air-conditioning system of  claim 1 , wherein the air-conditioning apparatuses each further including a temperature sensor and a humidity sensor. 
     
     
         9 . The air-conditioning system of  claim 4 , wherein the controller is configured to transmit the demand control command to keep the power consumption within the prescribed power amount when the number of people in the air-conditioned space detected by the human sensor is smaller than a predetermined number of people. 
     
     
         10 . The air-conditioning system of  claim 4 , wherein the controller is configured to transmit the demand control command to keep the power consumption within the prescribed power amount when illuminance in the air-conditioned space detected by the illuminance sensor is smaller than a predetermined illuminance.
